UNITED STATES? PATENT OFFICE.-

WILLIAM ARTHUR SMITH BENSON, OF LONDON, ENGLAND.

JUG OR VESSEL FOR CONTAINING LIQUIDS.

SPECIFICATION forming part of Letters Patent No. 605,071, dated June 7,1898.

Application filed July 26, 1897. Serial No. 646,028. (No model.)

To all whom itmay concern/:-

Be it. known that I, WILLIAM ARTHUR SMITH BENSON; architect, a subject'of the Queen of Great Britain,residingat 39 Montagu Square, London, inthe county of Middlesex, England, have invented certain new and usefulImprovements in Jugs or other Vessels, of which the following is aspecification.

'The object ofmy invention is to construct a jug or vessel in whichwater will remain hot much longer than in a jug of ordinary constructionand similarly in which iced Water may be preserved for a considerabletime.

In the accompanying drawings, Figure 1 is an elevation of avessel'constructed in accordance with my invention, and Fig. 2 shows avertical central section thereof.

The vessel consists of an-outside jacket a, which is formed witha spoutand handle and a receiving vesselc, which fits Within the jacket a. Thereceiver is tapered at its upper end, and it may be throughout, and itis formed at its extreme upper end with an an-- nular flange turnedoutwardly.- Around the upper end of the receiver, outside the flange,there is a packing-ring d of compressible and expansible material, suchas vulcanized indiarubber.

Within the jacket, near the top thereof, is a recess or seating a toreceive the packingring, so that when the receiver is inserted Thereceiver is inserted into the jacket from the bottom, and the bottom ofthe receiver may then be closed by cardboard or wooden disks e and f anda metal disk 9, which-may be held in place by soldering or in anyconvenient manner. l

The space between the receiver and the jacket may eitherbe left void ormay be more or less filled with a non-conducting material which willcheck radiation between the interior and the exterior and will check thecirculation of the air confined between the receiver and the jacket. bhinged to it.

The elastic ring cl and the parts in connection therewith form a simpleand inexpensive joint connecting the receiver and jacket. The ring beingcompressible admits of the receiver 0 being readily thrust upward intoits The outside? jacket has a lid' place within the jacket a. The ringentering the annular recess or seating a in the jacket is securelyretained therein. The ring when gripping the tapered end of the receiverat its neck or smallest part holds the receiver, so that it cannot risefromv its place.

The elasticity of the ring allows the receiver to expand freely whenhotliquid is poured into it. The ring separates the parts the one from theother, so that there can be no metallic conduction from the receiver tothe jacket or lossof "heat thereby. The ring makes an air-tight closingto the insulatingspace between the receiver and the jacket.

I claim as my invention 1. A temperature-retaining vessel, consist-. ingof a jacket and a receiver, both tapered and smaller at the neck thanbelow, the re-. ceiver being formed with an annular flange at its upperend turned outwardly, and the jacket being formed with an annular recessopposite the flange of the receiver, an elastic compressible ringembracing the receiver at its neck or'smallest diameter below the flangeand arranged in therecess in the jacket, and a plate closing the lowerend of the jacket afterthe receiver has been inserted.

2. The combination of a tapered receiving vessel having an annularoutwardly-turned flange at its upper end, an outside tapered jacketformed with an annular recess opposite the flanged end of the receivingvessel, an elastic compressible ring seated in the recess of the jacketand arranged below the flange of the receiving vessel, and means forclosing the bottoms of the jacket and the receiving vessel.

3. A temperature-retaining vessel consisting of a jacket and a receiverboth tapered andsmaller at the neck than below, an elastic ringembracing the receiver at its neck or smallest diameter, an annularrecess or seating in the neck of the jacket to receive the elastic ringwhen the receiver isthrust up intoits place within the jacket, and a:plate closing the lower end of the jacket after the receiver has beeninserted. 7
